Abstract
Abstract This invention pertains to the production of cigars or cigarettes which have a tobacco substitute filler and a wrapper and which on burning produce vapors and condensates free from nicotine, and which have only a minute amount of tars. The tobacco substitute is made from carbon or graphite fibers, mat or cloth associated with an oxidizing agent. Other agents are added as needed or desired to improve texture or form, to give an improved burn, or to make the product more salable or economical to manufacture. The wrapper includes an impregnation of an ashing ingredient.
